Power Resistors Strategies These high voltage resistors are available in various designs and they are used for more specific purposes. Most manufacturers are focused on delivering designs of application and customer specific resistors. They usually come in low and medium volume. These resistor types are available for various applications. Each of them retains the technology and application issues’ understanding.

These manufacturers know that users are trying to prevent risking and compromising the component and system failure. They do this through using standard products of resistors. These do not get the exact specification being asked but they are actually the closes materials available. There have been manufacturers that are offering products for high voltage resistor that are application-specific and are available in low to medium volumes.

A high voltage resistor major application is circuit protection sensitive elements present in a power supply. Other applications include motor control, medical devices, anti static systems, balancing and emitter resistors, military systems (RADAR, SONAR) and divider circuits. The capability to manufacturer depends on some elements. These involve the TCR or temperature coefficient of resistor, wattage ranges, ohmic ranges, and voltage.

The high voltage resistors provide special requirements which are available on high voltage applications. The typical carbon film resistors’ ¼ watt are available in various electronics ranges from 250 volts to 500 volts which has been under the kilovolt level required. The voltage limitation is set through the power dissipation issues like a 10k resistor with one kilovolt across it dissipating 100 watts.


When it comes to lower current applications, the device physical length has been about 1 cm which indicate from 5 to 10 kilovolt arching around the body of a resistor has been a great problem. Some high voltage resistors utilize the spiral path of dark metal oxide. This is actually available in ceramic. This is another type of high voltage resistor. This is known as tiger stripe resistor. Its capability of peak voltage is usually the body length function and they come in voltage that is ranging about 50 kiloVolt. An important type of resistor is the non-inductive tubular resistor or the bulk ceramic one. Due to extremely resistive volume of the materials, these resistors have been well pulsed power. When compared to metal film or wire wound counterparts, they will be higher. This is to make them perfect for high energy pulse and rapid energy dumping works.

Shunt resistors have been integrated in the parallel form with the component or instrument in order to divert the electrical current. These have been providing the alternative paths for current just in case there is failure and may be utilized to complete the reduction in the sensitivity of input from an input line going to the ground.

The current shunt resistor has been generally passive and low resistance electronic devices that have been utilized in measuring DC (direct current) and alternating current (AC) through a voltage drop that the currents had created all through the resistance. Shunt resistors’ electrical specifications include ohms current rating, and power rating. Other specifications involved are the power coefficient of the resistance, temperature coefficient of the resistance and the resistance tolerance.


Ohm is used to measure the material’s opposition into the flow of electricity circuit. On the other hand, the temperature coefficient of resistance (TCR) is the resistance change with change in temperature. On the other hand, the PCR or power coefficient of resistance refers to the temperature that had risen due to self-heating. The resistance in current-sensing shunts varies. It usually ranges from about 100 µO up to 500 mO. Shunt resistors have been utilized in the applications of current conversion in which high precision has been required.

Shunt resistors’ physical specifications come in different forms. But these include the lead type as well as the resistor materials. A shunt resistor can be surface mounted, chassis mounted, through-hole mounted, and bolted. THT or the through-hole technology and SMT or the surface mount technology are both other popular and common mounting styles. Other lead types available are axial leads, radial leads, gull-wing leads, screw terminals, J-leads and tab terminals.

Shunt resistors without leads are also available and they can be wire wound, metal film, metal oxide, carbon film, ceramic, metal alloy, thin film, and thick film. A carbon shunt resistor is comprised of resistive, solid, ceramic, and high temperature materials. These were connected by metal contacts. The metal alloy shunt resistor contains more than 2 metallic elements and the wire wound shunt resistor has been composed of thin wire winding into the ceramic rod.

Shunt resistors differ in terms of packing methods because some passive electronic elements are packed in the reel tape assemblies along with a carrier tape which embossed cavities for storing individual component. Some were packed in trails (trays) have been composed of fiber and carbon-power materials while they have been molded in a rectangular outline containing matrices of pockets that are uniformly spaced.
